4. Turn on the air supply and Press the knob,
allow the vacuum level to reach approximately
20-25 in Hg (50-60 cm Hg) and release the
knob (The gauge reading may be slightly less
in higher elevations but a proper vacuum
should still be reached within 3 minutes). Let
the system hold for 20 seconds to observe for
a drop in vacuum.
CAUTION
A drop in the gauge reading within 20
seconds indicates a vacuum leak in the
system, which will require locating and
rectifying the leakage before proceeding
further.
NOTE
During this procedure the radiator hoses will
collapse under the vacuum being generated
- this is normal.
5. Once the gauge has reached the desired
vacuum level and there is no drop in gauge
reading, turn the refill valve (red lever) on and
the coolant will start to fill the cooling system.
A system without a vacuum leak will fill in
about 3 to 4 minutes.
CAUTION
If the refill tube end comes out of the coolant
during the refill process, air will be pulled
into the system and the entire procedure will
need to be repeated. Kindly ensure to
maintain sufficient amount of coolant in the
container to avoid this issue.
6. Once the vacuum gauge reaches “0”, turn
refill valve off (red lever), check the amount of
coolant was added to system, if necessary
top-up the coolant to the specified level and
refit the pressure cap.
7. Start the engine and run until normal
operating temperature is reached. Allow to
cool and top-up coolant if necessary.
NOTE
If the amount of coolant specified for the
vehicle was not added to the system, repeat
the procedure from step 1.
